In this workshop, participants will engage in inquiry activities designed to emphasize critical thinking and scientific reasoning within the context of introductory astronomy. Content may include activities applicable to all science (e.g. logical fallacies, terminology, etc.) and activities specific to astronomy (e.g. shadows, lunar illumination, etc.) These activities are part of the Learning Critical Thinking Through Astronomy Project and its associated textbook (in development). Participants should bring notebook computers with wifi capability.
